The present application relates to a fiber optic connector holder for fiber optic telecommunications installations.
Installation of telecommunications equipment to support the current and potential future needs of a particular group of customers may make it desirable to install more capacity than the current customer base alone may dictate. Excess capacity may be installed to permit the easy addition of new circuits for new or existing customers. A telecommunications connection cabinet with such excess capacity may be pre-configured at a fabrication facility and installed in the field to include more circuits than are necessary to provide service to the existing customers. Prior to the linkage of these surplus or future expansion circuits to customers, it is desirable to provide for storage, organization and protection of the patch cords or other connection cables within the cabinet.
Such connection cables might include fiber optic patch cords terminated with fiber optic connectors. Fiber optic connectors include a polished end face, typically held by a ferrule, which permits positioning of the optical fiber held by the connector to receive and transmit signals another optical fiber or optical light source. It is desirable to keep these polished end faces as free of contaminants as possible to improve the transmission of light to and from the optical fiber held by the connector. Such contaminants which might adversely impact the transmission of light to and from the optical fiber include but are not limited to dust and finger prints.
Dust caps may be provided for connectors to protect the polished end face of the optical fiber. However, when such dust caps are in place, the connector is not capable of being received in known optical fiber adapters, such as those described in U.S. Pat. No. 5,317,663, and U.S. Pat. No. 6,347,888. The disclosures of these patents are incorporated herein by reference. A connector may be inserted into one of these known adapters for storage or pre-wiring of a cross-connection point, an interconnection point or some other type telecommunications switching or connection equipment with the dust cap removed. While the adapters might provide some protection from contaminants to a single connector inserted into an adapter, these adapters are not as effective as a dust cap in protecting the polished end face.
Fiber optic connector holders were disclosed in commonly-owned U.S. patent application Ser. No. 10/613,764, filed Jul. 2, 2003 and entitled Fiber to the Premise Cabinet. The disclosure of this application is incorporated herein by reference.
It is desirable to improve the known methods and apparatus for protecting the polished end face of a fiber optic connector within telecommunications equipment.
The present invention relates generally to fiber optic connector holders. More specifically, the present invention relates to a fiber optic connector holder including a housing with at least one cavity for receiving a fiber optic connector with a dust cap in place about a terminal end of the connector. The housing may be integrally molded with retaining structures for releasably engaging the fiber optic connector and releasable catches for mounting the housing at a mount location. The presence of a fiber optic connector within a cavity of the housing may prevent the removal of the housing from a mounting location.
The accompanying drawings, which are incorporated in and constitute a part of the description, illustrate several aspects of the invention and together with the detailed description, serve to explain the principles of the invention. A brief description of the drawings is as follows:
Reference will now be made in detail to exemplary aspects of the present invention which are illustrated in the accompanying drawings. Wherever possible, the same reference numbers will be used throughout the drawings to refer to the same or similar parts.
At the top of housing 12 is mounted a pivoting handle 26 to lift connector holder assembly 10 within the side guides and initiate and permit sliding movement of connector holder assembly 10. At the bottom of housing 12 is a slide handle or clip 28 which may operate to retain connector holder assembly 10 within the side guides in a retracted or an extended position.
As shown in
Housing 12 includes a plurality of mounting locations 32 for receiving and mounting connector holders 14. As will be described fUrther below, connector holder 14 includes a deflectable or movable mounting tab 34 and an opposing fixed mounting tab 36 on opposite sides of the connector holder. Movable tab 34 deflects inward into cavity 30 to permit passage of connector holder 14 between a pair of opposing sides walls 38 defining an opening 40 at one of the mounting locations 32. Once through opening 40 and beyond side walls 38, movable tabs 34 spring back into their original undeflected position. Side walls 38 are then trapped between tabs 34 and 36 to hold connector holder 14 at mounting location 32.
As described in the referenced patents and patent applications, mounting locations 32 may also be populated with fiber optic adapters to used in the optical connection of two optical fiber cables 16 and connectors 18. Such adapters are well known in the telecommunications industry. As shown in
As shown in the FIGS., above, housing 12 is generally angled from perpendicular to an axis of insertion A of connectors 18 into connector holders 14. While housing 12 is shown with two offset pairs of mounting locations 32, with each opening 40 of the pair generally aligned with each other, it is anticipated that all four mounting locations 32 may be offset from each other. Such a continual offset arrangement of connector holders 14 might generally follow the angle of housing 12. As shown in the referenced patents, housing 12 may also be configured with all the connectors holders in a line generally perpendicular to axis of insertion A.
As shown, there are four connector holders 14 providing eight cavities 30 for receiving connectors 18. Other numbers of connector holders may be provided and housing 12 extended or otherwise altered as necessary to accommodate more or fewer numbers of connector holders. Housing 12 may also be adapted to mount connector holders of difference sizes or configurations.
Referring now to
Within each cavity 30 is an inner surface 48 of an outer side 50, in which are located tabs 34 and 36. As shown in
As shown in
Referring now to
Each cavity 30 may also include structures 68 which engage releasable catch 19 of connector 18 to releasably secure connector 18 to connector holder 14. While connectors 18 are shown as LC format connectors and connector holder 14 is configured to releasable engage connectors of this format, it is anticipated that other brands, styles or formats of connectors and corresponding mating structures may be used on housing 42 within the scope of the present disclosure.
As shown in
Extending between cavities 30 is a longitudinal bulkhead 80 which extends from a bottom 82 of housings 42 and 142 to at least transverse bulkheads 74 and 76.
The extent of deflection required to position or remove connector holder 14 at mounting location 32 is shown in
To position or remove connector holder 14 at mounting location 32, movable tabs 34 are depressed inward, deflecting arms 62 about proximal end 64 so that inner surface 72 of arm 62 is positioned inwardly from inner surface 48 of wall 50 into cavity 30. Such deflection would not be possible with a connector 18 within cavity 30. With movable tab 34 depressed inwardly enough so that an outermost extension 70 generally aligned with wall 50, side 38 of opening 40 can be removed from or placed between catches 54 and 56. Arms 62 are preferably made of a resilient deformable material that will return to the undeflected location shown in
It is anticipated that a mounting location for connector holder 14 may be defined in a variety of locations, wherever temporary storage of a connector with a protective dust cap in place may be desired. The configuration of connector holder 14 (and 114) provides security against accidental removal from a mounting opening when connectors are positioned within cavities 30, so that equipment with such connector holders may provide control of preinstalled cables in telecommunications equipment during transport, handling, installation, or environmental disturbances.
It is anticipated that connector holders and mounting locations according to the present disclosure may be incorporated into bulkheads which are part of telecommunications equipment, such as that described in U.S. Pat. No. 6,556,763, issued Apr. 29, 2003, the disclosure of which is incorporated herein by reference. It is also anticipated that connector holders and mounting locations according to the present invention may be incorporated into drawers which are part of telecommunications equipment, such as that described in U.S. Pat. No. 6,504,988, issued Jan. 7, 2003, and in commonly-owned U.S. patent application Ser. No. 09/900,465, filed Jul. 6, 2001, the disclosures of which are incorporated herein by reference.
The above specification, examples and data provide a complete description of the manufacture and use of the composition of the invention. Since many embodiments of the invention can be made without departing from the spirit and scope of the invention, the invention resides in the claims hereinafter appended.
